Application filed April 18, 1910. Serial No. 556,218.

To all whom it may concern Be it known that I, HENRY IVEBER, Jr., acitizen of the United States, residing at Chicago in the county of Cookand State of Illinois have invented certain new and useful Improvementsin Work- Feeding Mechanism for Stitchingdda-chines, of which thefollowing is a specification.

This invention relates to improvements in work feeding mechanism forstapling or stitching machines, particularly adapted for use in machinesfor stapling boxes of considerable length, and one of the objects of theinvention is to provide improved means for feeding the work to thestapling mechanism and improved means for varying the degree of movementof the feeding mechanism.

A further object is to provide improved means for adjusting the workfeeding mechanism. with respect to the work support to accommodate workof different thicknesses, and for maintaining a uniform pressure of thefeeding mechanism upon the work in any of its adjusted positions.

A further object is to provide an improved support for the work andimproved means for raising and lowering the support with respect to thestapling mechanism,

A further object is to provide an improved guide for directing the workto the stapling mechanism, and improved means whereby the guide may beadjusted to accommodate the work of varying widths.

A. further object is to provide an improved gage for positioning thework upon the support.

A further object is to provide an improved machine of this characterwhich will be simple, durable and cheap in construction, and effectiveand efficient in operation.

To the attaimnent of these ends and the accomplishment of other new anduseful object-s as will appear, the invention consists in the featuresof novelty in the construction, combination and arrangement of theseveral parts hereinafter more fully described and claimed and shown inthe accompanying drawings illustrating an embodiment of the invention,and in whi-ch Figure l is a front elevation of a stapling machineshowing an attachment applied thereto constructed in accordance with theprinciples of this invention. Fig. 2 is a top plan view of Fig. 1. Fig.8 is a sectional view on line 3 3 of Fig. 1. Fig. 4 is an enlargeddetail elevation of the operating mechanism for the feeder. Fig, 5 is anenlarged detail sectional view showing the support for the feeding wheeland the means for adjusting the same with relation to the work support.Fig. 6 is a detail sectional view on the line 66 of Fig. 3. Fig. 7 is adetail sectional view on line 77 of Fig. 1. Fig. 8 is a detail sectionalview on line 8-8 of Fig. 4.

Referring more particularly to the drawings and in the presentexemplification of the invention, the numeral 10 designates generallythe stapling mechanism which is mounted upon a suitable support 11, andwhich stapling mechanism receives its motion from a pulley wheel 12adapted to be driven from any suitable source of power. Spaced from thesupport 11 and to one side thereof is another support 13 which may beconnected with the support 11 in any suitable manner, preferably bymeans of a connection 1 1 at the base thereof. This support 13 isprovided with a head 15 and a work supporting arm 16 is pivotallymounted upon the head 15 as at 17 Work support 16 may be of any desiredlength and configuration, but is preferably in the form of a narrow bar,as shown more clearly in Fig. 2, with its forward end 18 terminating ata point slightly beyond the stapling mechanism 10. The rear end 19 ofthe work support 16 projects for any desired distance beyond the support13, and is provided with a slot 20 (shown more clearly in Fig. 7)through which a fastening device 21 passes. This fastening device alsopasses through the head 15 of the support 13, and the portion 22 of thefastening device 21 which passes through the slot 20 is of a diametersomewhat smaller than the width of the slot, so that the work support 16may be adjusted about its point of pivotal support 17 to raise and lowerthe forward end thereof with respect to the stapling mechanism.

Connected to the rear extremity 19 of the work support 16 by means of apivot 23 is a bar or rod 24, the free extremity 25 of which isscrew-threaded. A similar bar or rod 26 is pivotally connected as at 27to a portion 28 of the base of the support 13, and the free extremity 29of this bar or rod 26 is screwthreaded. The threads on the extremity ofone of the bars or rods 24, 26 are right hand threads, while the threadson the extremity of the other bar or rod are left hand threads, and

these threaded extremities are connected by means of a collar or nut 30,around which is arranged a hand operating wheel 31. \Vhen the hand wheel31 is rotated, the nut or collar 30 will draw the rods 24, 26 towardeach other, or separate the rods to raise or lower the extremity 18 ofthe work support 16, according to the direction of rotation of the handwheel, and in. order that this hand wheel and collar may serve tocounterbalance the work support, they are constructed of heavy material.

In order to regulate the adjustment the nut or collar is preferablyprovided with graduations 32, and an index or pointer 33 is supportedpreferably by one of the bars or rods 24 to cooperate with thesegraduations 32.

The platform or table 34 is provided for holding the supply of work, andis preferably arranged adjacent the standard or upright 13, and restsupon the head 15. A bracket 35 may also be provided which projectslaterally from the head 15 to assist in supporting the table.

A support 36 is mounted upon the upright 11 and an additional support 37is mounted upon the head of the stapling mechanism. Journaled in thesupport 36 is a shaft 38, which is provided with a gear wheel 39 (seeFig. 4) and the forward extremity of this shaftprojects beyond thesupport 36 and is enlarged as at 40 to form a tubular extension. Thistubular extension is bifurcated as at 41 for a purpose to be hereinafterset forth. A second shaft 42 is journaled in the support 36 and a gearwheel 43 is secured to one end thereof. This shaft 42 is arrangedadjacent and parallel with the shaft 38, so that the gear 43 will meshwith the gear 39 on the shaft 38. A ratchet wheel 44 is also secured tothe shaft 42 and is adapted to impart rotation to the shaft 42 whenrotated. An oscillating arm or member 45 is pivotally supported by oneend, preferably upon the shaft 42, and a ratchet dog 46 is pivotallymounted upon the arm or member 45, so that when the latter isoscillated, it will cooperate with the teeth of the ratchet 44 to movethe latter in one direction when the arm or support is moved in onedirection, and to ride over the teeth when the arm or support is movedin the opposite direction. An elastic member 47, such as a spring, isprovided, which tends normally to hold the ratchet dog in engagementwith the ratchet teeth. Any suitable means may be provided foroscillating the arm or support 45, and a suitable and efficient meansfor accomplishing this result comprises a shaft 48 which is mounted insuitable bearings 49 on the support 36. Secured to one extremity of theshaft 48 is an arm 50 which is provided with a slotted extremity 51 intowhich a pin or lug 52 projects, and this pin or lug is supported by thearm or member 45, so that when the shaft 48 is rocked within itsbearings, the arm 50 will be correspondingly rocked, and this movementof the arm will impart an oscillating movement to the arm or supportSecured to the other end of the shaft 48 is another arm 53 which ispreferably arranged opposite to the arm 50. Journaled to the extremityof the arm is an antifrict-ion roller 54 which engages a cam 55 mountedupon the operating shaft of the stapling mechanism, and which cam issccured for rotation with the pulley 12. \Vhen the cam is rotated, theshaft 48 will be rocked in its bearings, and will through the medium ofthe arm 50, arm or support 45 and dog 46, rotate the ratchet 44. Thisratchet will in turn rotate the shaft 38 through the medium of themeshing gears 43, The anti-friction roller 54 may be held in position tobe engaged by the cam in any desired or suitable manner, preferably bymeans of an elastic member 56, such as a coil spring or the like. Thiselastic member surrounds a bar or rod 57 with one extremity restingagainst a head 58 on the bar, and the other extremity against a lug 59on the arm 50. The free extremity of the bar 57 projects through abearing 60 on the support 36 and is threaded, as at 61, to receive anutor collar 62. lVhen it is desired to vary the degree of rotation of theshaft 42, the nut or collar 62 may be adjusted to adjust the bar or rod57 longi tudinally, and this longitudinal adjustment thereof will varythe angle of the arm 53 with respect to the cam 55 to move theantifriction roller 54 on the arm toward or away from the cam, and inorder to indicate the degree of adjustment, the rod 57 is provided witha collar 63 having graduations 64 thereon, and an indicator 65 isprovided which cooperates with the graduations 64-. The collar 63 isconnected for rotation with the nutor collar 62 so that when the latteris rotated, the graduations 64 will be adjusted with respect to theindicator 65.

The support 37 on the head of the stapling mechanism is provided with atubular portion 66 having a shoulder 67. A bearing 68 is provided withan extension 69, which latter projects into the tubular portion 66 ofthe support 37. The bearing is supported and connected with the support37 by means of a rod or member 70 which projects into the tubularportion 66 of the support 37, and is screw-threaded as at 71 and thisthreaded portion 71. projects into a threaded recess 72 in the extension69 on the bearing 68 for supporting the bearing. The rod or member 70 isprovided with a collar 73 within the recess 66 and is adapted to engagethe shoulder 67 and to be held in engagement with said shoulder by meansof an elastic member 74, such as a coil spring or the like whichsurrounds the rod above the tubular portion 66 of the support 37 and oneextremity thereof rests against the support and the other extremityagainst a nut or collar 7 which is secured to the rod by a suitablefastening device 76. With this construction and when it is desired toadjust the bearing 68 with respect to the support 37, all that isnecessary is to rotate the sleeve or collar 75, and this will in turnrotate the rod 70. l' hen the rod is rotated, the threaded extremity 71thereof will draw the extension 69 of the bearing 68 into the tubularportion 66 of the support 37, or force the latter out of the tubularportion, according to the direction of rotation of the sleeve or collar7o. The elastic member 74: will always tend to hold the collar T3against the shoulder 67.

Journaled in the bearing (58 is a shaft 7 7 which is provided with alaterally projecting portion 78, in one end thereof (see Fig. 3) andthis extremity is adapted to be inserted into the sleeve 40 on the shaft38, so that the lateral projection 78 will enter the bifurcation in thesleeve. The forward extremity of the shaft 77 projects through andbeyond the bearing 68, and secured thereto is a feed wheel 79 which maybe of any ordinary and well known construction. This feed wheel 79 islocated directly above the top of the work support 16, and is adapted tobe moved into engagement with the work as it rests upon the support.When the feed wheel is in engagement with the work and a rotary motionis imparted to the shaft 7 7 from the shaft 38, the feed wheel '79 willbe rotated to advance the work, and the degree of rotation of the feedwheel is controlled by the adjustment of the arm 53 through the mediumof the collar 62 and the bar or red 57 in the manner as already setforth.

The feed wheel 79 is normally elevated out of engagement with thesupport 16 by the elastic member 74:, and when the work is in position,the feed wheel is depressed or moved into engagement with the work. Anysuitable means may be provided for accomplishing this result. A suitableand efficient means comprises a member 80 which slides through asuitable bearing 81 preferably mounted upon the support 37. The upperextremity 82 of this member 80 is preferably of a hook-shaped formation,the extremity of which engages the collar 75, which latter is preferablyrecessed slightly to receive the extremity. The other extremity 83 ofthe member 80 is connected to an arm or lever 84:, one extremity ofwhich is pivotally supported as at 85 to a suitable support, and theother extremity is connected by means of a link 86 to the treadle 87,which latter actuates the clutch mechanism, and which clutch mechanismcouples the pulley 12 to the main operating shaft of the staplingmechanism in the ordinary and well known manner not necessary toillustrate. Suflice it to say that the feed wheel 79 is lowered intoengagement with the work simultaneously 1 with the throwing in of theclutch for controlling the pulley 12.

In order to regulate the degree of adjustment of the feed wheel 79, withrespect to the w rk support 16, an indicator 88 is pro vided which isconnected preferably to the bearing 68 and cooperates with graduations89 arranged on any suitable support, prefe ably the support 37.

The work support 16 may be provided with any number of anti-frictionrollers 90, so as not to retard the advancement of the work thereon, anda supplemental support 91 may be provided which is also provided withanti-friction rollers 92. This supplemental support cooperates with thework support 16 and is adjustable laterally with respect thereto, so asto accommodate work of varying widths, and this supplemental support maybe supported in any desired or suitable manner, preferably by means ofbrackets 98, one extremity of each of which is pivotally mounted, as at9%, to one side of the work support 16 and the other extremities areloosely connected by means of fastening devices 95 to the supplemental.support 91. hen it is desired to adjust this supplemental supportlaterally with respect to the main support 16, all that is necessary isto loosen the fastening devices 95 and move the supplemental support tothe desired position, such motion being permitted by the pivotal actionof the brackets 93. After adjustment, the fastening devices may betightened to secure the parts in position.

In order to direct the work to the stapling mechanism as it is advancedby hand along the work support 16 from the table or platform 34 intoposition to be engaged by the feeding wheel 79, suitable guides areprovided which comprise spaced horizontal members 96, 97. One of thesemembers 96 is supported from the main support or standard 11 in anysuitable manner and extends over the top of the work support 16 and isspaced therefrom. This member 96 is provided with a depending flangedportion 97 which projects below the surface of the work support andadjacent the rear face thereof, and anti-friction rollers 98 areyieldingly supported in the portion 97 so as to engage the portion ofthe work extending across the rear face of the support 16. The member 96is provided with a suitable aperture through which the feed wheel 79projects. The edge 99 of the member 96 adjacent the work as it isadvanced toward the stapling mechanism is deflected as shown, and theextremities of the depending portions 9'7 are deflected as at 100 toassist in guiding the work beneath the member 96. The member 97 whicheoope'ates with the member 96 is also provided with a deflected portion101 corresponding to the portion 99 of the member 97 and this member 97is also provided with a depending portion 102 similar to the portion 97of the member 96. The extremities of this portion 102 are deflected asat 103 and assist in directing the work beneath the members 96, 97.

The member 97 is supported by means of bars or rods the free extremitiesof which slide in suitable guides 105 provided on the support 100, andwhich support is mounted upon the upright 11. Suitable fastening devices106 may be provided for holding the member 97 in its adjusted position.One of these bars or rods 10% may be provided with graduations 107 andan indi cator 108 is provided preferably on the member 90 whichcooperates with the graduations.

With this improved construction it will be apparent that after thesupports and guides have been adjusted, the work may be fed by hand fromthe table or platform and the deflected or bent extremities of themembers 96, 97 and the extremities 100, 103 of the depending portions 97102 will direct the work into proper position with respect to thestapling mechanism. In order to prop e'rly position the work withoutnecessitating accurate adjustment each time a new piece of work is fed,a suitable gage 109 is provided and this gage is mounted for adjustmenton the work support 16 and longitudinally thereof. The gage projectsabove the top of the work support as shown more clearly in Figs. 1 and 2to form a shoulder against which one edge of the work is adapted toengage and a fastening device 110 is provided for securing the gage inposition. Having once adjusted the gage 109, it will be apparent thatthe work may be readily fed by hand from the table 3st and properlypositioned with respect to the stapling mechanism by causing the rearedge of the work to engage and rest against the shoulder formed by thegage 109.

The position in which the staples are inserted into the work withrespect to each other may be varied by adjusting the collar ('32 to movethe anti-friction roller 54 toward or away from the cam 55. lVhen it isdesired to set the staples close together, the anti-friction roller isadjusted some dist ance away from the axis of rotation of the cam, butwhen it is desired to set the staples farther apart, the anti-frictionroller is adjusted toward the axis of rotation of the cam.

With this improved construction, all that is necessary after the partshave been adjusted, and when it is ready to insert staples into thework, is for the operator to take his position with respect to themachine so that he can readily remove the work from the supply and movethe work along the work support 10. After the work has been properlyadjusted, the t-readle S7 is depressed and the mechanism is operated toinsert a staple. After the insertion of each staple, the feedingmechanism will advance the work to the proper position and according tothe degree of rotation of the feeding wheel 79 as the machine may beadjusted. By the provision of the members 96, 97, it will be apparentthat after one corner of the work has been inserted thereunder and theoperator should release his hold of the work, the work will not fallfrom the work support to the round, but will be maintained upon the worksupport by means of the members 96, 97 and their depending portions 97.It will also be apparent that the elastic member 74 will be alwaysmaintained under the same tension, no matter to what position thehearing may be adjusted by the member 70.

In order to prevent the overthrow of the feed wheel 79 an elastic member111 in the form of a coil spring is provided which surrounds a portionof the shaft 49. between the enlarged portion and the bearing, so as tocreate a friction on the shaft which will act as a brake to preventoverthrow.

In order that the invention might be fully understood, the details ofthe foregoing embodiment thereof have been thus spec-illcally described,but
